I've created a multicam group. Everything is working great except for one thing. I want the "A" camera to always be displayed in the upper left, the "B" camera to be in the upper right, "C" camera lower left, "D" camera in the lower right. When a camera drops out (camera shuts on and off), the source monitor does not keep displaying the camera in its place. Is there a way to make it stay in the same place?
